BAOS SDK v2  1.0.1
An SDK providing access to IP-BAOS devices through BAOS binary protocol version 2.x
GetParameterByte.cpp

This sample shows how to read paramter bytes via he connection API

Usage:

GetParamterByte <ip_address>
// e.g.:
GetParamterByte 10.0.0.102
Note
Another possibility is via the device API.
